Fastwanabe said:I'm encountering the same issue the OP had, "Judder" while re-applying the throttle. OP fixed it with the CA but I don't have one. I emailed Grin and this is what he suggested......
"There are two ways............................................ the values of 2500 and 2.5 will be more appropriate".
I have yet to do this since my rear derailleur was destroyed while the motor was "juddering". I will recieve my rear derailleur this Saturday and will report back. What suggestions do you guys have? Thanks
Grin also gave me the same suggestions when I asked how to solve my judder problem.
I played a week with those settings and that didn't help at all.
The Phaserunner has a serious judder problem in combination with BBSHD /Ultra and apparantly also BBS02.
Someone at Grin should have a serious look into that issue!
Raising the minimum voltage in the CA so that the motor is always engaged cures most of the judder symptoms.
But it's just a workaround for a bad design / bad settings?
Anyway, you don't have the CA so that setting will not help your judder.
But maybe you could try the following:
The Phaserunner has a "Throttle start Voltage setting" (Under Advanced / Throttle + Brake Parameters)
Try lowering that to a value that is under the min. voltage out of your throttle. (my throttle is around 0.9V on idle)
For example 0.8V, that should always engage your motor. Maybe that could solve it?
Keep us posted.
